What is the Geocoding MCP Server?

The Geocoding MCP Server is a tool that provides geocoding services through the Model Context Protocol (MCP). It can convert addresses into geographical coordinates (such as latitude and longitude) via the Nominatim API and supports reverse geocoding (converting coordinates into addresses).

How to use the Geocoding MCP Server?

This server can be called through an MCP client (such as Claude Desktop). Simply add the server information according to the configuration instructions, and you can directly use the geocoding function in an environment that supports MCP.

Applicable Scenarios

Suitable for application scenarios that require geographical location queries, such as map services, location analysis, logistics planning, etc. It is particularly suitable for use in combination with AI assistants that support the MCP protocol (such as Claude Desktop) to enhance users' geographical information processing capabilities.

Main Features

Geocoding
Convert addresses into latitude and longitude for positioning and spatial analysis.
Reverse Geocoding
Convert latitude and longitude into specific address information to facilitate users' understanding of locations.
Compatible with MCP Protocol
Can be seamlessly integrated into AI assistants that support the Model Context Protocol (such as Claude Desktop).
Open Source and Scalable
The source code is open under the MIT license, supporting custom extensions and secondary development.
Advantages
Provides accurate geocoding services and supports multiple address formats.
Compatible with mainstream AI assistants (such as Claude Desktop) for easy integration.
An open - source project with good community support and technical documentation.
Easy to deploy and use without complex configuration.
Limitations
Relies on the Nominatim API and may be subject to API access restrictions or rate limits.
Only supports basic geocoding functions and does not include advanced spatial analysis capabilities.
May not be accurate enough for very complex address parsing.

How to Use

Install Node.js
Ensure that your system has Node.js version 18.0.0 or higher installed.
Install the MCP Server
Install the Geocoding MCP Server package via npm.
Configure the MCP Client
Add the server configuration in an MCP - supported client (such as Claude Desktop).
Use the Geocoding Service
Enter an address or coordinates in the MCP client to obtain geographical information.

Usage Examples

Find the Latitude and Longitude of Beijing
A user wants to know the exact geographical location of Beijing for use in a map application.
Find Street Information Based on Coordinates
A user has a set of latitude and longitude and wants to confirm the corresponding address information.
